Installation
Protect pump from the elements by
installing in a basement, garage, tool
shed or pump house. Install the pump
so the center line of the pump is as close
as possible to the water level. Keep
installation area clear to provide access
for service and maintenance. Protect the
pump against flooding and excess
moisture.
Make sure the pump has adequate
ventilation. The surrounding
temperature should not exceed 100°F
(38°C) or nuisance tripping of the motor
may occur.
PUMP PIPING INSTALLATION
Use new pipe for best results.
Galvanized or plastic pipe can be used.
When using galvanized pipe, provide
independent supports for both suction
and discharge piping near the pump to
avoid strain on the pump. Minimize use
of elbows and fittings to reduce friction
loss. Refer to the friction loss chart for
specific information.
Increase diameter of suction or discharge
piping if length is over 50 feet.
SUCTION PIPING
Install foot valve
or strainer screen
over intake of suction piping.
Never use pipe smaller than 2” in
diameter for suction piping.
The suction
pipe must be kept free of air leaks. For
horizontal runs, lay pipe from the water
source so the upward slope is at least 1/2”
per foot. This eliminates trapped air. The
threaded inlet of the pump is 2” NPT.
Do not install suc-
tion piping near
swimming areas.
